Although the exchange houses offer a highly demanded service, the truth is that they are centralized entities. Therefore, once you transfer your criptomonedas there, you must be aware that, from that moment on, the platform has the ability to control those funds beyond you. And, if the administrators want to, never return them.
It is for this reason that exchange houses (and, in general, all types of companies) should be used, already regulated, or, at least, with some time operating and widely known. There are already cases of such platforms created only for the purpose of staying with the funds of the users. Some offer bonuses for joining in principle while posing hidden rates, and others are limited to not allowing withdrawals once sufficient deposits are given.
A case sounded was that of BitKRX in South Korea, where the administrators claimed to be even a regulated exchange related to the Korea Stock Exchange (KRX), when this was false.
Not only the exchange houses can be false: also the purses. In this case, it is not enough to stay among the best known portfolios, because the version that we are downloading (especially mobile versions) can be false.
Thus, an unofficial MyEtherWallet application managed not only to appear in the App Store, but to be one of the most downloaded from the store. Also, up to three versions of a presumed Poloniex app were listed on Google Play last year, and two of them were downloaded about 5,500 times before being dropped from the store. This, of course, gives scammers a unique opportunity to steal credentials and backgrounds: Your keys can be copied from the moment of your creation to empty your wallet later, or this can bring some “back entrance” by which end up leaving your Criptomonedas.
It is important, therefore, not to choose a random portfolio from the mobile stores, but to investigate what might be the best option for us depending on the team we possess and the functions and privacy to which we aspire. Made this choice, always use the official download page.
“Gifts” on social networks
This scam is quite similar to phishing, as it is to use imposter accounts on networks to deceive users. The difference is that through these accounts the funds are solicited directly instead of only the confidential information, under the promise that a much higher reward will be received after transferred a rather small percentage in comparison.
In that sense, it seems an adaptation to the Criptomundo of the classic Nigerian scam, although it is dispensed with the story elaborated on someone in trouble and resorted to the personification of celebrities in the ecosystem or out of it, as Vitalik Buterin and Elon Musk, Who suddenly announce that they are going to give away a certain amount of criptomonedas (usually ETH) to those who send another amount first to the indicated address.
The procedure is that the cybercriminal is created an account identical to that of some celebrity, with the same name, photograph and description; And there he publishes that he is willing to give Criptomonedas if first they send another amount. The users of the network, noting in the name of the account instead of the user (who always accompanies with @), usually think that it is really about that person. So they send the funds and they even share the post.
The favorite network for this kind of scam is Twitter, although it has also appeared on Facebook and Telegram.
It should be mentioned that, in the world of Criptomonedas at least, the only true “gifts” are the so-called faucets (pages that offer a minimum amount of criptomonedas in exchange for performing small tasks) and the airdrops, where the administrators of some New token send a small percentage to the owners of another (in Ethereum is very common) as a means of publicity, without asking anything else in return.
